Whether you can go straight to security after checking in online in 2026 depends on your luggage and destination. If you are traveling domestic with only a carry-on bag and have a mobile boarding pass, you can indeed head directly to the security checkpoint. However, if you have checked luggage, you must first visit a bag-drop counter or a self-service kiosk to tag and drop your suitcase. For international flights, the rules are stricter; even with online check-in, many airlines require a document check at the counter to verify your physical passport and any necessary visas or ETIAS/ETA authorizations. Some airports in 2026 have implemented "Digital Identity" lanes where you can skip the counter if your passport was scanned via the airline app, but this is not yet universal. Always check your digital boarding pass; if it says "This is not a boarding pass" or "See Agent," you must stop at the check-in desk before proceeding to security.
